OMVs-associated T3SS1 effectors are located on the outer surface of OMVs. OMVs were isolated from cultures of Salmonella strains producing HA-tagged SipA, SipB, SipC, SopA, SopB, SopE2, or SseD. OMVs treated or untreated with proteinase K were precipitated with trichloroacetic acid (TCA) and subsequently analyzed by immunoblotting using anti-HA antibody. SseD protein located in the lumen of vesicles and an integral membrane protein OmpA of OMVs were used as controls.
